Abstract
A method that embeds a message into a document containing a number of glyphs and extracts said message from a degraded version of said document. Each symbol of the message is represented as a geometrical relationship of two discrete sets of pixels, in which the pixels in each set are adjacent. The pixels associated with the glyphs selected from the document are combined with the discrete sets of pixels to produce modified glyphs that contain the embedded message.
Claims19
A method for embedding a message into a document including a set of glyphs, comprising:
- representing a symbol of a message to be embedded in a document as a geometrical relationship of two discrete sets of pixels, in which the pixels in each set are adjacent;
- and
- combining pixels associated with a glyph in the document with the two discrete sets of pixels to produce a modified glyph in the document, wherein the symbol of the message is embedded in the modified glyph.
A document stored on a readable media, the document including an embedded message, comprising:
- a glyph rendered on a document;
- and
- at least two discrete sets of pixels combined with pixels associated with the glyph rendered on the document, such that a geometrical relationship of the two discrete sets of pixels is suitable for extracting a symbol of a message embedded in the document.
